I smoked some baby backs today. I rubbed them last night and wrapped them and let them sit in the fridge overnight. I put them in the Smokette at 1pm. I had three slabs and cut them in half, and put three halves on each of two grills. I put these in the two lower positions and then I put some bacon on the top rack. at 4pm I went out and popped the door. The bacon on the top rack was nice and brown, but the bacon under the vent hole had an ugly gray spot on it.
When I opened the door, I removed the rack of bacon, moved the bottom grill of ribs to the top, and put the grill from the bacon in the bottom position and put in a pan of beans, with the bacon ripped up in the beans.
When I pulled everything out at 7:30, the slab of ribs that was under the vent had the same ugly gray spot. What caused the spot? The ribs were great, but we didn't eat the two bones that had the spot.
